This leadership shift occurs as OpenAI prepares for a potential IPO, facing increased competition and market share challenges, making Brockman’s role in driving revenue and innovation critical.
OpenAI Power Shift: Greg Brockman Takes Helm Amidst IPO Preparations

OpenAI has seen a significant shift in its leadership structure, with President Greg Brockman now at the helm of the company's most crucial and profitable projects. This consolidation of power follows the official stepping down of Fidji Simo, who previously served as OpenAI's product and business chief.
Simo's Departure and Brockman's Expanded Role
Simo, a former executive at Meta and ex-CEO of Instacart, cited chronic illness as the reason for her departure. She had been diagnosed with postural orthostatic tachycardia syndrome (POTS) in 2019 and had taken a medical leave in April. On Thursday, she announced her transition to a part-time advisor role.
Brockman, a co-founder of OpenAI, had already assumed product responsibilities during Simo's medical leave. He will now officially oversee OpenAI's ChatGPT product business, go-to-market teams, enterprise divisions, and compute initiatives. In a post on X (formerly Twitter), Brockman expressed his gratitude for Simo's contributions, stating, "I am deeply grateful for all Fidji has done for OpenAI and to advance our mission, and for the opportunity to have worked alongside her for the past few years."
Pressure Ahead of IPO
Reporting directly to CEO Sam Altman, Brockman faces the significant challenge of driving revenue and validating OpenAI's reported $852 billion valuation. This increased pressure comes as the company prepares for what is expected to be a landmark initial public offering (IPO). OpenAI confidentially filed its IPO prospectus with regulators in June but has reportedly delayed its public debut until next year.
Market Challenges and Competition
OpenAI is navigating a fiercely competitive landscape. The company is facing intense pressure from rivals such as Anthropic, Google, and Elon Musk's XAI. Furthermore, the proliferation of cheaper open-weight models, particularly from China, is contributing to market saturation.
Sensor Tower data indicated that ChatGPT's market share fell below 50% for the first time in March. In response, OpenAI has been actively promoting its AI coding assistant, Codex, to attract and retain users.
Leadership Continuity and Past Alliances
The company does not plan to hire a replacement for Simo. Instead, Sarah Friar, OpenAI's finance chief, and Jason Kwon, the strategy chief, will continue to report directly to CEO Sam Altman. This arrangement reinforces the close working relationship between Altman and Brockman, who co-founded OpenAI in 2015.
Their alliance was notably demonstrated in late 2023 when Brockman resigned in solidarity after Altman was temporarily ousted as CEO, only to return days later. Altman himself emphasized their partnership in a blog post at the time, stating, "Greg and I are partners in running this company. We have never quite figured out how to communicate that on the org chart, but we will."
Legal Battles and Future Vision
Brockman and Altman were also central figures in a high-profile lawsuit filed by Elon Musk earlier this year. Musk alleged that OpenAI had reneged on its founding commitments to remain a nonprofit entity. During his testimony in federal court in May, Brockman defended the startup's early years and its mission, testifying, "I think the tech we are developing is transformative. This is going to be the most important technological shift in human history." Ultimately, Musk lost the case when an advisory jury found he had waited too long to sue.
